TL;DR: It is shown that a SNP, 538G → A (rs17822931), in the ABCC11 gene is responsible for determination of earwax type, and this is the first example of DNA polymorphism determining a visible genetic trait.
Journal ArticleDOI
HLA-DQ is epistatic to HLA-DR in controlling the immune response to schistosomal antigen in humans.
TL;DR: It is concluded that the HLA-DR and DQ molecules, which are controlled by the distinct genes in the MHC multigene family, regulate immune response and immune suppression and that the gene for Hla-DQ is epistatic to that for H LA-DR in controlling the immune response to schistosomal antigen in humans.
Journal ArticleDOI
Participants' understanding of informed consent in clinical trials over three decades: systematic review and meta-analysis
Nguyen Thi Thanh Tam,Nguyen Tien Huy,Le Thi Bich Thoa,Nguyen Phuoc Long,Nguyen Thi Huyen Trang,Kenji Hirayama,Juntra Karbwang +6 more
TL;DR: The proportion of participants in clinical trials who understood different components of informed consent varied from 52.1% to 75.8% and investigators could do more to help participants achieve a complete understanding.
Journal ArticleDOI
Cerebrospinal fluid lactate concentration to distinguish bacterial from aseptic meningitis: a systemic review and meta-analysis.
Nguyen Tien Huy,Nguyen Th Thao,Doan Tn Diep,Doan Tn Diep,Mihoko Kikuchi,Javier Zamora,Kenji Hirayama +6 more
TL;DR: To distinguish bacterialMeningitis from aseptic meningitis, CSF lactate is a good single indicator and a better marker compared to other conventional markers.
Journal ArticleDOI
